So lets do a break down of what we know so far about the Cleric class break down.
First and foremost a cleric is a healing class. There will be two very defined cleric types from what I have read, ones that are ok at healing but can be offensive and then those who are beast at healing but are mostly defense. Trion has let us know that clerics will either being wearing mail (woot) or cloth depending on the way you decide to take your character. Clerics will also be able to choose from a wide selection of weapons from major 2h head smashers to the more arcane getting the staff type weapons.
Trion so far has let us know about three different sub classes of cleric. The three sub classes so far are Purifier, Inquisitor, and Sentinel.
To quote Trion lore on the Purifier:
The tradition of the Purifier begins with a baptism by fire, a test of faith from which only the strongest souls emerge. Those who pass are reborn as masters of the curative secrets of fire, able to heal the most grievous wounds with a searing touch.
These Clerics also draw upon a pact with their long-dead ancestors as the source of their offensive power. While Purifiers wreathe their allies in flames, they can unleash a spirit vanguard to visit wrath upon their foes.
Strengths
Purifiers dedicate themselves to mastering the healing properties of fire, and as such are potent support Clerics who can burn away disease and instantly cauterize the most horrific wounds.
Weaknesses
Purifiers are not known for their offensive capabilities, and while they are capable of marshaling the fury of their ancestors to strike down foes, they rapidly lose ground against the focused assault of a determined melee combatant.
Purifier History
In the time of the Blood Storm, a witch-doctor named Talos Roda fled into the volcanic jungles of Aegea when his village was overrun by the Dragonian servants of Maelforge. For days, he lay in a fever, his wounds festering as his life slipped away. At the end of the fourth night, Roda found himself surrounded by flickering motes of flame and the whispering spirits of his ancestors. These sprits promised him vengeance if he formed a pact with them and became their conduit to the physical world.
I am intrigued by the baptism by fire stuff, and I think it will be interesting to see this develop over time. I think this will more then likely be a class I try out seems right up my ally with all the SUPPORT stuff there.
